SANTA CLARA — Undrafted running back Austin Walter won himself a 49ers roster spot at last weekend’s rookie minicamp.

Walter, a Rice University all-purpose machine, wasn’t the only addition to the 49ers on Monday. Offensive lineman Willie Beavers was claimed off waivers from the Chicago Bears and journeyman linebacker LaRoy Reynolds signed a one-year deal.

“I would like to thank the 49ers organization for giving me this opportunity that’s not given to most people and I promise to make the most out of it,” Walter wrote on his lengthy caption under the Instagram picture of him signing what’s believed to be a three-year deal.

According to his Rice bio, Walter tied for the national lead with 17 plays of at least 30 yards via rushing, receiving and kick returns. He ranked 14th in all-purpose yards (1,580), and he was 9 kick-return yards shy of becoming the first Rice player to have at least 500 yards rushing, receiving and returning kicks in a season.

Beavers (6-5, 324) was a 2016 fourth-round draft pick of the Minnesota Vikings, and he’s spent much of the past two seasons on practice squads with the Vikings, Bears, New England Patriots and Seattle Seahawks.

Reynolds (6-1, 240) has appeared in 84 games over his stints with the Jacksonville Jaguars (2013-15), Bears (2015), Atlanta Falcons (2016-17) and Philadelphia Eagles (2018). He ranked second on the Eagles with nine tackles on special teams.
